Abstract

The structural changes in cryodeformed copper are studied during long-term (1-2 year) storage at room temperature. The material is found to be unstable: grain growth is detected. The revealed structural instability casts doubt on the use of cryogenic deformation to form a nanocrystalline structure in copper.
